Sunday Downtime - All Evolve Media Sites are being migrated to a new data center Sunday Dec 11, 2016. The migration will occur during an 8 AM to 2 PM (Pacific Time) maintenance window. We will have up to 1 hour of downtime for any of our sites.

Go to Youtube and try searching for "make up men/guys" or "using a concealer". It's much more helpful than written text, you can actually see what you are supposed to do and can see the result and decide if it could work for you.
Also going to some counters, MAC for example and asking for some advice on colors/shades and application methods is helpful. Some concealers work better with applied with a small brush, some are better when blended in with fingers and so on.
Also taking before and after pics is helpful, so you can see how it turns out, so you don't end up with reverse raccoon eyes or orange spots all over your face.

thank you so much for answering, yeah I've find on youtube some great techniques, however I'm not yet convinced I should buy some; especially when I see the prices and then obviously the new budget I should think of: I guess I'm gonna stick to "try" to buy some designers' labels for now but thanks anyway

Some men have to wear make-up as part of their work (in the media) so it's not that much of a leap to experiment with using it in other situations. And we should all be free to have fun with this easy way to express ourselves - after all, it washes off in the end.
